Worked on enhancing the safety and correctness of ADXL decoder drivers within the nrfconnect/sdk-zephyr repository, focusing on embedded systems and driver development using C. Addressed a critical bug by replacing unsafe pointer casts with uintptr_t arithmetic, which eliminated build warnings and improved type safety in offset calculations. This update resolved -Wint-to-pointer-cast warnings across multiple ADXL decoders, reducing the risk of undefined behavior in sensor data handling. The changes contributed to more reliable sensor data paths and improved the maintainability and stability of continuous integration workflows, reflecting a careful and detail-oriented approach to low-level systems programming and driver reliability.
